This invention relates to textile machines and is particularly concernedwith machines for the twisting and winding of yarns, such as ringspinning, flier spinning and cap spinning machines.

In machines of this type the spindles are generally arrangedsubstantially vertically, and the traversing of the yarn being spun uponthe bobbins or other yarn packages is effected by the vertical movementsof a lifter rail, which carries either the bobbins on which yarn isbeing wound or guide means for conducting such yarn to the bobbins. Thelifter rail is actuated by means of vertical rods known as poker rodswhich carry the lifter rail on their upper ends and are verticallyreciprocated in guides or sliding bearings, each rod having a chainattached to its lower end, the chain passing over a flanged wheel orchain sprocket and being secured to a horizontally reciprocatingtraverse rod. In a long machine, having many spindles arranged in line,the lifter rail may be divided into sections each carried by two suchpoker rods appropriately spaced from one another along the length of thelifter rail section.

According to the present invention a twisting and winding machine forthe collection of a series of yarns comprises a series of verticalspindles, a horizontal lifter rail adapted to be reciprocated verticallyfor traversing yarn upon bobbins mounted on said spindles and aplurality of vertical poker rods for carrying and actuating said lifterrail, said rods being disposed in pairs along the length of the lifterrail, the rods of each pair being disposed at substantially the samedistance along the length of the rail, one attached near the front edgeand the other near the rear edge of the rail. The arrangement of thepoker rods in pairs in this way gives more even support to the lifterrail and reduces any tendency to the deflection or distortion thereof,without increase in the moving weight, each of th pair of rods employedhaving approximately half the weight of a single rod as employedheretofore in the same position along the length of the rail butdisposed in the middle of its width. It also allows the vertical run ofthe chain by which the rods are operated to be located centrally betweenthe two rods, being attached to the middle of a yoke by which the lowerends of the rods are connected; this relieves the poker rods of thebending moment arising in previous constructions in which the chain isconnected to a small horizontal projection extending laterally from thebottom of each rod. In addition, the use of a pair of rods permits themto pass one on each side of the spindle rail instead of passing througha hole formed in the middle of orporation of America,

the spindle rail for the purpose as when a single rod is employed. Thespindle rail is the rail, generally non-reciprocating, carrying therotating bobbins in cases where the lifter rail carries the thread guidemeans as in a ring-and-traveller device, or carrying the thread guidemeans where the lifter rail carries the bobbins as in cap spinningmachines.

For the guiding of the pairs of poker rods poker rod slides or bearingsmust be provided, and the bearings of each pair must be parallel to eachother within close limits in order that the poker rods may operatefreely and accurately and without hesitation. The machining of thebearings with the requisite degree of accurate parallelism is apt to beexpensive. It has been found however that a less expensive mode ofconstruction may be adopted by providing for some freedom of lateralmovement for one of the poker rods, the other being rigidly fixed at itsupper and lower ends to the lifter rail and to the connection betweenthe poker rods respectively. Thus the lower end of on poker rod may reston an adjustable tappet passing through a yoke by which the rods areconnected while the upper end of the rod has a bearing surface on whichthe lifter rail rests, lateral movement of th upper end with respect tothe rail being limited to means of a spring connection between it andthe lifter rail.

While the invention is applicable to twisting and winding machines ofthe difierent types referred to above, it is of particular advantage asapplied to ring spinning machines for the reason that the lifter rail ofa ring spinning machine,

having to accommodate in its width the diameter of a ring large enoughto encircle a full bobbin, is generally made wider than a lifter rail ina cap spinning or flier spinning machine. In consequence the poker rodsof each pair may be more widely spaced from one another and greateradvantage is obtained in respect of the rigidity of the lifter rail.

In ring spinning machines, in which the yarn fed to the bobbin passesfrom a balloon-guide or cordingly, means may be provided in conjunctionwith the traversing arrangement of the present invention for raising andlowering the balloonguide in phase with the lifter rail so as to keepthe balloon length constant or more nearly constant than if a stationaryballoon-grime" employed. For this purpose the balloon=guides were"corresponding to the spindles of each section of a lifter rail may bemounted on a common guide" rail extending across and carried-by theupper f ends of two vertical rods slidably mountedin ver tical bearings,and actuatedby the same mechanism as the double poker rods describedabove;

Thus, each vertical rod can b'e dis pose'd'clos e to one of the pairs ofpoker rods carrying the lifter rail and can be driven by a nection fromthe yoke joining the poker rods. In order to deal with any slight linkand lever con lack of parallelism in the vertical rods, thes'ect'ion ofrail carried thereby may be divided in the middle and joined we ilexilolingsli'ght play betweenthe two partsi H y ay of exarhple, one formof'riri'g spin'r'iin mac ine in accorda'ri'ce" with the pres nt inven:
